After electroplating other metal on the surface of aluminium and aluminium extrusion , it can significantly improve the surface physical or chemical properties, for example, electroplated silver on the surface can improve the electrical conductibility; electroplated copper, nickel or tin on the surface, it's to make aluminium alloy easy to weld; electroplated chromium is to improve wear resistance; In the decorative aspect, actually mostly adopted electroplating chromium. Aluminium and aluminium alloy surface electroplating have long been tried and used in actual production. The factors that oxidizing material existing between aluminium alloy and electroplated layer, the difference thermal expansivity between aluminium alloy and metal plating, pinhole and residual electroplating solution in electroplated layer etc.caused badly coating adhesion. Long time using will flake peeling off immediately after plating, even in the field of surface treatment, aluminium and aluminium a...

https://haluminium.com/ Homogenizing Treatment In Alloy 6063, the dissolving temperature of Mg2Si is 520 ℃, and Al-Mg-Si three-phase eutectic temperature is 595 ℃, the actual burning temperature is lower than 595 ℃, so homogenization should be treated between 520-595 ℃. After homogenization, the following changes occurred in Alloy 6063 structure: 1), Coring Segregation disappeared. 2), Mg2Si is dissolved in α (Al12Fe3Si2), and unbalance eutectic disappeared. 3), The acicular β(Al9Fe2Si2) is transformed into a spherical α (Al12Fe3Si2), and the iron-containing phase particles are refined. Through the above changes, the extrusion performance and aluminium profile quality will be greatly improved: The disappearance of coring segregation will reduce the inhomogeneity of metal flow during extrusion and improve the surface finish of extruded profiles; The decrease and refining of large unbalance phase Mg, Si particles and Al-Fe-Si phase particle in the structure, will redu...

In 2017, the investment and construction order of China's aluminium smelting industry was further standardized, and the momentum of production capacity growth was clearly contained. The overall performance of aluminium consumption has been relatively stable, but the real estate and other sectors have weakened the traditional consumption of aluminium, the aluminium exports have declined, and the electrolytic aluminium stocks remain high. The average price of aluminium products rose sharply from a year ago, and the industry was making a big profit, but the profit level fell back in the fourth quarter. In the first quarter of 2018 is facing the traditional consumption off-season, together with the trade friction cases of aluminum foil, aluminum plate will affect parts of aluminum exports, and the effects of policy factors on the supply side has appeared, so electrolytic aluminium a glut on the market will remain in the short term, but benefit from control policy continuity, capac...

Today let's talk about our vehicle, especially the family car. When we read the configuration instruction of car, we often see the details about cylinder block of the engine. At present, the cylinder block of the gasoline engine is divided into cast iron and cast aluminium . In the diesel engine, the cast iron cylinder is the majority. In recent years, with the rapid development of automobile industry, cars have rapidly entered the life of ordinary people, and the fuel economy of vehicles has been gradually taken seriously. To reduce the weight of the engine, it can save oil.The weight of the engine can be reduced by casting aluminium  cylinder block. From the perspective of use, the strength of the cast aluminium cylinder is light-weight, which can save the fuel by reducing the weight. In an engine with the same displacement, the engine of the aluminium cylinder can reduce the weight of about 20kg. For every 10% reduction in the vehicle's weight, fuel consumption can ...

Aluminium profiles are aluminium materials with different cross-section shapes through hot melt and extrusion. The production process of aluminium profiles mainly consists of three processes: melting, extrusion and colouring (including oxidation, electrophoretic coating, fluorine spraying, powder spraying, etc.). The aluminium profiles are divided into: 1. Industrial aluminium profile: mainly used for aeroplanes, trains, industrial radiators, automobiles, electrical appliances, etc. 2. Aluminum alloy profile for building: mainly used for building doors and Windows, curtain walls, indoor and outdoor decoration and architectural structure. Surface treatments are divided into: 1. Anodized aluminium: the surface of the profile is oxidized by anodic oxidation, electrolytic colouring or organic colouring. 2. Electrophoresis coating aluminium: the surface of the profile is combined with anodic oxidation and electrophoresis. 3. Powder spraying aluminium: the surface of the pr...

The non-ferrous metal of aluminum is a light, soft, easy to oxidation in air, so people come up with a way, it is aluminum oxidation process, in its outer grow a protective film, durable, and can be dyed colorful color, the feast for the eyes. Anodising, or anodic oxidation, is an electrolytic process that deposits a chemically stable oxide layer on the surface of the aluminum. The resultant oxide film is thicker and stronger than aluminum's natural oxide covering.The principle of aluminum anodes is a process of decorating and protecting the aluminum and its alloys. In the process of alumina film is formed on aluminum made by direct current under enough voltage through a suitable sulfuric acid electrolyte, the object is the aluminum anode, and by another material or special graphite sheet (lead) as the cathode, electrify time grew out of the required thickness of oxide film. After the production of the film, except for some aluminum, the next step is to tint. In general, the...

We talked about two factors that affect the quality of oxide film: Electric Current Density and Temperature , now, we talk about the third factor -- Time. Under the same conditions of solution concentration and other processing technology, with the extension of anodic oxidation time, the generated oxide film will also be gradually thickening (within a certain range), the aperture gap (or pore space) will increase too which is good for dyeing. Under the same process conditions, on the contrary, if the anodic oxidation time is shortened, the generated oxide film will be thin, and the aperture gap (or pore space) becomes less and has trouble dyeing dark. Most of aluminium manufacturers’ anodic oxidation time is less than 20 minutes; except for some special situation, electrochemical polishing (Click on the link to learn more about electrochemical polishing) for example, shortens the anodic time to maintain brightness after anodizing. It’s necessary to extend the anodic time when ...

In 2017, The aluminum market continues to rise. In 2017, the domestic and foreign aluminum market has been boosted by the two major policies of China's production capacity and environmental protection. As of the end of December 2017, aluminum prices in the international market rose 26.6%, while domestic aluminum prices rose 17.5%. The aluminium market was dominated by China policy in 2017. In the first half year two policies had been introduced: Work Plan for Clearning up and Rectifying Illegal Projects in the Electrolytic Aluminium Industry (No. 656), and The Beijing-Tianjin-Hebei Region Measures for Prevention and Control of Atmospheric Pollution (2+26 policy). Under the influence of the two policies, China's electrolytic aluminum production capacity and production had declined month by month since June. But after prices soared, stimulated the part of the compliance of new production and spare production capacity and production capacity, the annual output of ele...

1. The principle of electrophoresis technology The electrophoresis is basically the same as the traditional light and transparent electrophoresis. The anode electrophoresis is carried out under the action of direct current.With the action of the electric field, the coated particles with charge are moved to the coated workpiece, which precipitates the electrophoresis coating deposited on the surface of the aluminum profile, forming a layer of film.The difference lies in the different types of coatings and the slightly different devices. The electrophoretic coating includes acrylic resin, melamine resin, pigments, solvents, neutralizing agents, additives and other ingredients. Through the application of thermal fixing in the viaduct layer in the particle, the shape of the micro-concave coating during the process of baking was basically unchanged in the baking process, and the appearance of the film was formed uniformly.The degree of extinction can be adjusted by the ratio of high ...

The influence of extrusion process on oxidation coloring is mainly the influence of mold/die design, extrusion temperature, extrusion speed and cooling method on the surface state and tissue uniformity of extruded profiles. Mold design should be able to make the material fully fit, otherwise, it is easy to appear bright (dark) with defects, the same profile may appear on the color separation; At the same time, the mold/die state and profile surface extrusion pattern also affect the oxidation coloring. Extrusion temperature, speed, cooling and cooling time are different so that the profile is not uniform but also produce color. Anodic oxidation has important influence on electrolytic coloring of chromatic aberration, especially in the process of vertical oxidation production line is easy to appear the two color, vertical oxidation groove depth of 7.5 m, bath and easy to produce temperature difference, temperature has important effect on the anodic oxidation, high temperature, li...

https://haluminium.com The cause reason for the molten metal splash when die casting. 1. Cover halves combine imprecisely and have the big gap. 2. The mold clamping force is not enough. 3. The die-casting machine is flexible, and the mounting plates of cover half (fixed die) is not parallel. 4. Support span is large, and the injection pressure (force) deforms the sleeve plate, engendering molten metal spouting. Methods of adjustment 1) Reinstall the mold 2) Increase the mold clamping force 3) Adjust the die-casting machine, ensure the mounting plate of cover half (fixed die) and moving die maintain mutual parallel. 4) Add support plate on the movable mold, increase the stiffness of the clearing. The factors influencing the working life of the pressure nozzle jet: 1. The material and quality of the nozzle jet. 2. The fit clearance of the press charging barrel and jet nozzle. 3. The concentricity of the mold and press charging barrel while installing. 4. Co...
